I dislike this style as it's not normally used in the kernel.
Most would use another tab indent on the utf16s_to_utf8s line
if the line didn't fit, but this would is more common:

	result = utf16s_to_utf8s((wchar_t *)str->string.pointer,
				 str->string.length, UTF16_LITTLE_ENDIAN,
				 str_buf, sizeof(str_buf) - 1);

	plat_dev = platform_device_register_simple(DRV_NAME, 0, fjes_resource,
						   ARRAY_SIZE(fjes_resource));

etc...

Is this function used in this compilation?
If not, it's odd to add code that isn't used.

Is it better to make the 2nd argument a
struct resource * rather than a void * ?
